What does Osmosis mean?
Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane. The important thing to remember is that osmosis is the movement of WATER ( or other solvent ) not the particles dissolved in the water.
Why did the water gummy bear get bigger?
the water gummy got bigger because if you think of a net around the gummy bear the water can get into the net because its small but the sugar and the salt cant because its bigger and the water can get into the net!

Equipment

 Beaker









Beaker - A beaker is a glass container with a flat bottom and a small spout for pouring. It is used in the chemistry lab for mixing, heating, and stirring liquids. Beakers come in various sizes and are shaped like a cylinder.

Conical Flask









This type of flask is used as a container for chemical substances, or to heat or boil liquids. It does not allow liquids to spill easily. It is also used in titration.

Funnel









It is used to channel liquid or fine-grained substances into containers with a small opening

Measuring Cylinder








graduated cylinder is a piece of laboratory glassware used to measure the volume of liquids.

Evaporating basin 








An evaporating dish is used to evaporate solutions - that is, to turn them from a liquid state into a gaseous (gas) state. They are often made from ceramics.
